This invention relates to an apparatus for reproducing sound and type of apparatus general y known as phonoaphs, in the use of whichsound is repro,i uced from records preferably iof the disc type. In carrying out the invention either' electro-magnetic or` electro-static or other means may be employed in the reproductionof the sound.

I am aware that heretofore various devices have been made for use in phonographs whereby it is possible to automatically repeat the reproduction of sound from a given record and also to continuously and successively rel '15 produce the `sound from a series of records.

The object' of my invention, however, is the provision of an apparatus in the use of which it is not only possible to repeat asoften as may be desired the re roduction of sound from a given record an to successively reproduce the sound from a plurality of records, but also to utilize a plurality of records and to automatically reproduce the sound from the records successively, for reproducing the sound from any desired record,

and to make it possible to automatically reproduce the sound from any desired succes-t p sion of records lrrespective of the manner or sequence in which theyV may be placed in '30 the apparatus.

In carrying out the invention I employ -a device for supporting and revolving the records when placed preferablyl in vertical and suitably s aced positions, to ether with a carriage an devices associate therewith including a sound reproducer,and means operative in the actuation of the apparatus for so moving the carriage and the devices associated therewith that the sound reproducer adjacent record discs, set and moved to reproduce the sound' recorded on the faces thereof', either successively or alternately, and automatically shifted in such a manner as to reproduce the sound recorded on' the successive record discs in'any desired manner orsequence at the option of the operatorvof the apparatus, as will behereinafter more particularly described. v

Fig. 13 is a similar view of the end of the othlr guide arm and the cam associated therewit In carrying out the ,invention the apparatus is mounted in a suitable casing comprising a front, rear and side walls. As illustrated the front wall is indicated at 15, the 'rear wall v at 16 and the side walls at 17 and 18 respeces referably included in iate wall 19 extending to the front and rear walls. The mechanism as illustrated is operated by the motor 20. This may be mount- 9o ed in any suitable manner and in an desired position. .On the shaft 21 of the motor shaft 29 complementary to thestub shaft 27 10o and similarly journaled or mounted in the wall 15. The belt is crossed and also passes around the pulley 28. By this construction, as will be understood, the shafts 27 and 29 are turned in opposite directions by the motor.

A pulley 30 is mounted on a shaft 31 which is journaled in the wall 19 in alignment with the shaft 27. Passing over this pulley 30 als is a belt 32. A pulley 33 is mounted on a shaft 34 also journaled in the Wall 19 and the belt 32 also passes around the pulley 33. A pulley 35 is mounted on a shaft 36 which is journaled in the Wall 19 in alignment with the shaft 29. A belt 37 passesl around the pulley 35 and also around the pulley 33. lAs clearly indicated in Fig. 1 of the drawing on the shaft 34 there is also a friction pinion 38. On the shaft 31 there is a clutch collar 39 connected with which there is a friction disc 4() adapted to engage a friction/ disc 41 carried by the pulle '26, the clutch collar and its disc being sli ably mounted on the shaft 31 and adapted to turn therewith. Similarly on the shaft 36 there is a clutch collar 42 associated with which is a friction disc 43 ada ted to engage with a friction disc 44 carrie by the pulley 28. Associated withthe clutch :collars is a Vshift lever 45 ivotally mounted at 46, and having yoke end; 47 and 48 adapted respectively torengage the circumferential notches in the clutch collars 39 and 42. This shift lever 45 is actuated by an operatin lever 49 pivotally mounted on a pin 50 an connected at one end to an arm 51 carried by the shift lever order, as will be understood, to move either one of the friction discs40 or 43 intov contact'A with its re-- spective friction disc 41 or 44.

Engaging with the friction pinion`38 there is a friction wheel 52 the hub 53 thereof being journaled in a bearin provided therefor in the wall 19. Exten g fromthe hub 53 there is a stub shaft 54. Associated with the stub'shaft there is a support shaft 55. In suitably spaced positions this shaft 55 Ais provided with circumferential grooves 56. One end of the shaft 55 is mounted-in a bearing 57 supported on the wall 16, while the opposite en of the shaft Y is provided with a collar 58 adapted to engage the stub shaft 54. This shaft 55 is normally maintained in an operative position by means of the spring 59 or otherwlse. The shaft 55 functions as a supportfor the disc re :ords' whichA are placed' in s aced positions-thereon.

T e records are spaced b sleeves 60. each one of which is provided wit spaced arms 61 and `62 adapte Ato engage the records for maintaining the same 1n `tion,' as illustrated at a predetermined A's'tance. Each of these sleeves is fitted with cams 63 and 64, as illustrated in Figs. 10 and`11, and which will be hereinafter described.'- The sleeves as also illustrated in Fig. A10 are each preferably fitted with a screw plug 65 located m a recs friction discs 72 and 82. f

66 provided therefor in the plug and carrying a pin 67 actuated by a spring 68 for normallyen aging the inner end of the pin against t e shaft 55 and preferably one of the circumferential grooves 56 therein. As illustrated in the drawing the record discs are desi nated at 69 and as will now be understoo spaced positions, which is preferably vertical on the shaft 55 which passes through the central opening in each disc whereby through the turning of the shaft in either direction the records mounted thereon will be simultaneously revolved in a corresponding direction.

Suitably journaled in the upper portion of the frame member 15 there isa stub shaft 7 0.

Mounted on this stub shaft 70 is a pulley 71 'with which there is associated a friction disc 72, A belt 73 passes over the hub pulley 53 and also over the pulley 71 .whereby this pulley is driven from the hub pulley 53. In a position above and suitably spaced from the stub shaft 70 there is another stub shaft 74 also suitably journaled in the frame member 15. On this stub shaft there is a pulley 75 and associated with the pulley 7 5 there is a friction disc 76. A belt 77 passes over the pulleys 71 and 75 whereby the pulley 75 is driveny from the ulley 71.

Suitably journaled in t e frame members 16 and 19 and in alignment with the stub shaft 74 there is a shaft 78 which may be called a carriage shaft and which is clearl indicated in Fig. 4 is referably flat side Mounted on the shaft 8 adjacent the stub shaft 74 there is a clutch disc 79 and a sleeve 8O adapted to turn with and slide upon the shaft 78 and to be connected with and disconnected from the ulley 75 by means of the discs 76 and 79. so suitably journaled in the frame members -16 and 19 there is a shaft 81. This shaft is provided with a suitable screw threadand is in alignment with the stub shaft 70. On the Aend of the shaft 81 adjacent lthe stub shaft 70 there isa clutch disc 82 and a sleeve 83 mounted to slide on the shaft and to turn therewith and to en age with the friction disc 72 whereby the s aft 81 may be turned by the pulley 71 through the l suitable shift lever 84 engagesl the sleeves 80 and 83 and is actuated as hereinafter described to shift the discs 79 and 82 in such a manner as to cause them respectively to be disengaged from or to be engaged with the correspon ing friction dise associated therewith.

are maintained in their respective Mounted on the shafts 78 and 81 there is a carria e 85. This carriage -comprises a 'suitable rame havin arms ,86 and 87 through which both the'sai shafts pass. Mounted on the shaft 78 and between suitable guides 4provided therefor in the carriage there 1s a pulley 88. This dpulley is mounted on the shaft so astosli e thereon and turn there- 45 reproducermay 'be of any 'desired type but with, it being understood that the carriage is adapted 'to slide on the shaft 78 and tobe shifted on this shaft by the shaft 81, the screw threads of whichV engagewith the screw threaded portions of the arms 86 and 87 through which this shaft 81 passes so that when the-shaft 81V is turned in one direction or the other the carriage .85 is correspondiny moved -in one direction or the other.

y ounted to `turn freely on Athe shaft 81 and immediately withinthe arm -86 is la pulley 89. Passing over this pulley and also over the pulley 88 there is a belt 90 whereby when the shaft 78 fis revolved and the pulley 88 turned'thereby the pulle'y89 is also turned on the shaft 81. This pulleyl 89 has a hub 91 which lits upon and is connected to a sleeve 92 4by means of the screw threads as indicated in F" 5, or otherwisey- At one end the sleeve 92 is anged as indicated at 93 and also-as illustrated in .,Fig. 5 this flange 93 .preferably lies Immediately within the carriage arm 87 whereby these parts are mounted to extend and fit between these carriage arms.

Mounted on the hub'.91 of the pulley 89 lthereA isga series `of. rings 94 and 95 and .96.

These rings extend between the flange '93. and

f the pulley 89 and are adapted toturn on the hub 91. Connected with-the ring 94'tliere is a guide arm 97 adapted, as hereinafter de. scribed, to contact with the periphery of the record disc 98 and similarly-connected tothe 'ring 96-there is a guide arm 99 adapted to bear against thevperipheryj of another disc record which is indicated at 100. The guide arm 97 extends to one sideof the .shaft 81 -and the guide arm 99 to the other side thereof. The purposes and functions of theseA guide arms will be hereinafter more particularly described. j A

- .Extending from the ring 95 there is a re` producer arm-101. This reproducer arm 101 carries a frame 102 between theoppositely disposed parts of which a reproducer 103 is pivotally'mounted, as indicated at 104. The

is preferably an electro-magnetic or electrostatic-reproducen At one end the reproducer i .has aA projection 105 'in whichthere is -a V- shaped notch and at the opposite end there is a needle arm 106 carrying needles 107 and 108. At the l extremity of the needlearm there is a screw head 109 vfor maintaining the needles in posi-tion.

The outer end 110l of the reproducer frame is provided with projections 111 and 112. The reproducer vis normally maintained in position, which may be a neutral position, by means of springs 113 and 114 connected at corresponding ends in the sides of the reproducer and adapted at'their opposite ends to yieldingly engage V.the side members of the reproducer frame,

as is clearly shown in Figs. 4 and 5 of the l drawing.

Connected to the guide arm 97 therel'is a cam 115.' This camis made tojinclude a notch or recess 116, a cam face 117 and a projection-118 spaced therefrom. In" a similar nan-V ner the guide arm 99 is provided with a cam 119. This cam 119 is constructed to include a notch or recess 120, a cam face projection 122 spaced therefrom.

121 and a The cam is connected to' and carried by ,v i.

. the guide arm 97 bymeans of a cross arm 123 and in a similar mannerthecam 119 is" connected to and carried by the guideV arm 99,

by a similar cross piece.

Extending between the members 86 and 87 of the carriage 85 there is a. shaft 124.

Mounted on" this shaft 124 there is a sleeve' 125 extending from which there is a long arm 126 and a short arm 127. Thelong-arm is'adapted-to bear against the guide -arm 97 and when raised or lifted thereby to swing the short -arm 127 into contact with a shoulder on the guide arm 99 to thereby raise the same inv order to cause it to clear the records. On the shaft 124 is also a sleeve1-28 extending from which is along arm 1 29adapted to bear against the guide arm 99 and-a short. arm

130. -'When the long varm 129 is lifted 'or raised by the guide arm 99 it thereby swings f the-short arm 13() into Contact with a shoulder on the guide arm 99 to thereby raise the same, causing it to clear the records.. It will therefore be-u'nderstood that'the lifting of one of the guide 'arms causes the other guide arm to be raised so that .when necessary to shift the carriage both the guide. arms are.

'clear` of the `recordsirrespective of the diameters thereof.

Associated with. the reproducer-arm 101 there is a clutchadapted to engage the hub 91. VThe head-131 of this clutch may be made of any suitable material adapted to functionreproducer arm4 and parts associated therewith `will be swung or moved correspondingly. The clutch head 131 .is Vcarried by a plunger 132 mounted to move in a guide pro vided therefor-in the reproducer arm 101. This plunger is provided with'a-re'duced'end 133'on wlnch there'is associated a spring 134 for actuating the plunger to normally move the same and the clutch head toward the hub.

Swiveled on the reduced end A133 of the plunger there is -a disc 135 having notches 136 and 137 in the periphery, thereof.

105' ally engage the hubso that when thus engaged through the turning of the hub thewith the hub 91 and to engage the surfaces of the V-shaped notch at the end of the re- Cil producer 103 to swing the same to one side or the other of its neutral position and to thereby cause one of the needles to engage the face of a record. The guide arm 99 is provided with a projection 142 carrying a spring 143 adapted to cooperate with a pin 144 connected to and extending from the disc 135. Similarly the guide arm 97 is fitted with a projec` tion-145 carrying a spring 146 for cooperating with a pin 147 connected to and extending from the disc 135. The operation of these parts will be hereinafter more particularly described. 1 In the upper portion of the cabinet or casing there is a shaft 148 at-.one side thereof anda corresponding shaft 149 at the oppo site side thereof. lBoth these shafts extend between and are fixed in the'walls 16 and 19.

Mounted on these shaftsthere are series of cam devices 150. On each shaft there is one of these cam devices for each one oi the records mounted on the shaft 55. These cam devices are similarly constructed and placed on the shaft 148 in one position and on the shaft 149 in the opposite position. The cam devices 150 are moreover illustrated in detail in Figs. 8 and 9. Each of these cam devices, as will be seen from these figures, comprises a collar 151 and a hub 152 extending therefrom and mounted to turn freely on the shaft on which it isplaced.

Extending radially from each hub there is a series of spaced arms 153 and each arm 153 has a curved projection 154 extending therefrom which functions as a cam, as hereinafter described. The hub portion 152 is so constructed as to/include spaced recesses 155 which are intermediate of the arms 153. Moreover, eachof these cam devices includes a boss 156 anda projection 157. The boss 156 extends from one of the ribs intermediate of adjacent recess 155 and the projection 157 extends from the collar 151 intermediate of twoof the arms 153.

Also in the upper portion of the casing and in the same side thereof as the shaft 148 there is a shaft'158. This shaft 158 extends between and is mounted in the walls 16and 19 and is parallel with but below the shaft On the shaft 158there is a series of collars 159 corresponding in number with the number of cam devices 150 and consequently with the number of records on .the shaft55. Each collar 159 has an arm 160extending therefrom with a ball 161 at the extremity thereof. This ball is adapted to operate in the recess 155 in the hub of the corresponding cam device and is normally maintained in position therein by any s uitable spring or other tension means which may be applied either to the shaft or to each of the arms individually. Each arm 160 may itself be a spring and the shaft 158 fixed in position. In the opposite side of the apparatus there is a shaft 162 corresponding with the shaft 158. On the shaft 162 there is a series of collars 163, one of which is shown in Fig. 2 and each of which is provided with an arm 164 at the extremity of whichA there is a ball 165 adapted to cooperatewvith the recessed hub portion of the cam devices 150 mounted on the shaft 149. The balls 165 are each maintained in contact With the surface of the hub of the corresponding cam device by any suitable tension means, it being understood of course, that there is a collar 163 and its arm and spherical head for each of the cam devices on the shaft 149.

In the upper port-ion of the apparatus and on the same side as the shafts 148vand 158 there is another` shaft 166. This shaft extends between and is journaled in the walls 16 and 19 and is fitted with a plurality of collars 167 each having an arm 168 extending therefrom. lThe number of these collars corresponds to the number of cam devices on the shaft 148 and the arm 168 extending from each of these collars is sufficiently long to be engaged by any one of the arms 153 of the corresponding cam devices 150. The shaft 166 extends through the wall 19 and on the outer side thereof is provided with a crank 169. On the opposite side of the apparatus there is a shaft 170 corresponding to vthe shaft 166. On this shaft 170 there is a series of collars'171 each having an arm 172 extending therefrom, these collars and arms corresponding in number With the cam devices 150 on the shaft 149 and each arm 172 is sufficiently long to be engaged by any of the arms 153 on these cam devices on the shaft 149. The shaft 170 also passes through the wall 19 and on the outer side thereof is provided with a crank 17 3.

The crank 169 carries a pawl 174 adapted to engage in a notch 175 adjacent the corresponding end of the rod 176. The crank 169 and consequently the .shaft 166 are normally maintained in an initial position by means of a spring 177. In a corresponding manner on the opposite side of the apparatus the crankl 173 carries a pawl 178 adapted to 'engage a notch 179 adjacent this end of the rod 176 and the crank 173 and the shaft 170 are normall maintained in `their positions by a suita le spring 180 or otherwise. The rod 176, as illustrated in Fig. 3 is mounted on springs 181 and 182l and is adapted to be shifted in uides 183 and 184. A central portion of t e rod 176 is pivotally connected,

as indicated at 185, to the upper end of the lever 49 whereby in shifting the rod 17 6 from l 78 and the reproducerj shaft 81 is caused to turn. In the upper portion of the apparatus and at one side thereof there is still another shaftV 186 which extends between and is journaled in the walls 16 and 19. On this shaft there is series of collars 187 each having an varm 188 extending therefrom. The collars 187 and the arms 188 correspond in number with the number of cam devices 150 on the shaft 148 so that there is a collar 187 and an armv 188 for each of the records in the apparatus. At one end of the shaft186'there is a link 189. One end of this 'link is fixed on the shaft. The other end of thelink 189 is pivotally connected as indicated at 190 to one end of the arm 191of a shift rod. This arm 191 is mounted' in guides 192 and isfextended in an arm 193 at right angles thereto and integral therewith, or otherwise, thgvarm 193 being sufficiently long to extend over a crank 194 in a shaft 195.

At the opposite side of the apparatus thev shaft 186 has a counter part ina shaft196. Mounted on the shaft 196 there is a seriesof collars 197. Each of these collars 197 carries arms 198 and the number of collars 197 and the arms 198 correspond with the number of cam devices 150 on the shaft 149 so that there is one of these collars 197 and its arm 198 for each of the records mounted on the shaft 55. Secured" on one end of the shaft 196 there is a link 199. One end of the link 199 is secured lto the shaft and the oppo- 4site end is pivotally connected, as indicated at 200, to the end of an ax'1n201 of another shift rod. The arm 201 is mounted in guides ,202, and has an extension 203 at right angles thereto and which maybe integral therewith or suitably connected thereto. The'arm 203 also extends over thecrank 194 of the shaft 195.. This shaft 195' extends through slots 204.

i and 205 provided therefor in the walls 15 and 16- and is mounted on spring actuated plungers 206 and 207 so as to be yieldinglysupported and normally maintained in an initial position.

Pivotally connected at one end on the crank 194 there is a rod 208 which is movable in guides 209. The lower endof this rod 208 is ivotally'connected at 210 to'one end of a 11n 211 forming part of the shift lever 84. The link 211 is pivotally mounted on a pin 212 and carries a cross arm 213 having yoke complete this shift yoke end 214 is adapted to engage in the c1rcumferential recess of the sleeve 83, andthe yoke end 215 in the sleeve 80.

The carriage' 85 is fitted with terminals 216 for leads from the reproducer and the terminals 216 are caused to slideon and bear against trolleys 217 which exteriorly of the wall'16 or otherwise m-ay be fitted with terminals for lead wires to a suitable vacuum tube amolifving apparatus. The diameter of either one direction or ,the other.

the shaft 55 is necessaril limited by the diameter of the centering oles of the records and consequently the diameter of this shaft is relatively small. In some instances as will be understood, where a relativel large numberof records is to be employe and is provided for it may be necessary to employ one or more supports to maintain the shaft 55 in alignment. One of these sup orts is indicated at 219, in Fig. `1. At its ase the support rests upon the floor of the cabinet or casing andat its upper end it is provided with a bearing adapted to receive any one of the spacer sleeves 60. By this means, as will be understood the shaft 55 may be maintained in alignment irrespective of its length and the number of records it may support.

In the operation of the 'apparatus the various parts of the mechanism are driven by is, the reproducer arm and reproducer may be caused to move from4 the frontto the rear of the apparatus and to play .the records successively in this direction, or the reproducer arm and reproducer may be caused to move from the rear toward the front of the apparatus and to play the successive records when traveling in this direction. The arrangement, furthermore, is such that when desired any one or more of the records may be omitted, that is, unplayed when the reproducer arm and'reproducer are caused to travel in In the further explanation of the operation of the apparatus it will be assumed that in looking at the parts from lthe front thenearest face of each record will be called the obverse face and the distant face of each record vthe reverse' face, and that when swinging clockwise, when Viewed from the front of the apparatus, the parts are operated to play the record on the obverse face of the adjacent record discs and when moving counter-clockwise are operated to play the record on the reverse face of the next adjacent disc. It will be understood, of course, that when-playing the record 'on the reverse face of the disc the shaft 55 and the record thereon turn in one direction, whereasl when playing the records on the Iobverse face of the same or adjacent record discs the shaft- 55 and the records thereon must turn in the oppositewdirection.

For the sake of illustration it may-be' assumed that the reproducer arm and reproducer havebeenmoving counter-clockwise and playing therecordA on the obverse face of i the record 98 (see Fig. 1). During the playing of the record. vas hereinafter described,

Aiso

the reproducer arm is fnee to move on the hub 91 and the needle 107 is maintained in contact with the record so as to freely track in the groove thereof. After the playing of this record has been completed. the clutch head 131 engages the hub and the reproducer arm and reproducer continue to swing in a counter-clockwise direction by means of the motor operating the various parts as hereinbefore described to turn the shaft 78 and thereby the pulley 88 and through the belt 90, the pulley 89 and the hub 91. These members then continue to travel in this direction, as indicated in Figs. 4 and 5, until the reproducer arm and the reproducer frame have reached a substantially horizontal position as shown in Fig. 4. When this position o the reproducer arm has been reached the projection4 111 will have come into. contact with one of the arms 153 on the corresponding cam device on the shaft 148. Assuming that this cam device is set to be given a partial turn by the projection 111 the continued movement of the reproducer arm and the frame ycarried thereby causes this cam device to be given a partial turn wherein the corresponding ball 161 is caused to ride over the intervening rib between the adjacent recess in the hub of the cam device, thereby limiting and determining the extent vto which the cam device is turned. This occurs at the moment when the stop 221 carried at the end of the guide arm 99 comes into contact with the needle ar1n106 of the reproducer which determines the extent of the swinging movement of the reproducer arm relatively tothe frame carried thereby, it being understood that the upward swinging movement of the reproducer arm carries the guide arm 99 along with it until the free end of the guide arm 99 contacts with a stop 222 suitably connected to the frame, as indicated in Fig. 4.

Also as hereinbefore described the upward Swingin movement of the guide arm 99 swings itzhe long arm 129 and actuates the short arm 130 of the -bell crank lever which also swings upwardly the other guide arm 97 so that both guide arms are entirely free or clear of the upper edges of the record discs irrespective of the diameter thereof.

In the upwardmovement of the reproducer i arm the rod 139 has been free to move in the reproducer arm and consequently to ride over the projection 122 and the camy face 121 on the cam 119 which is actuated by the guide arm 99, it being understood that in this swinging movement of the reproducer arm the pin 138 has been employed. At the time'the cam l device is caused to turn -a partial revolution it operates the corresponding arm 168 on the shaft 166 causing the shaft to rock and to thereby swing the crank 169 suiciently` 'far to cause the awl 174 to engage in the notch 175 and'to shift the rod 17 6 from right to left, as viewed in Fig. 3, thereby swinging the operating 'lever 49 and' causing the reversal of the direction in which the carriage shaft 78 is revolved. This, as will be understood,

143 carriedby the cross arm connected to the guide arm 99. At this time the inner end of the rod 139 is permitted to engage in the recess 120 of the cam 119, then, as will be understood, the clutch head 131 is still in engagement with the hub 91 and the parts continue to descend. This motion continues until the guide arm 99 rests upon the periphery of the corresponding record' disc. When this action takes place, as will be understood, the guide arm 99 remains stationary and the `-reproducer arm and the parts associated therewith continue to descend. During this continued movement the inner end of theV rod 139 rides upon an inclined face forming part of the recess in the cam carried by the guide arm 99. As the downward movement of the reproducer arm continues the inner end of the rod 139 rides upon the cam face 121. In reaching this position this rod 139 is shifted from right to left' as seen in Figs. 4 and 5 andthis movement of the rod 139 causes the pin 141 carried thereby to contact with the face ofthe disc 135 and to thereby shift the i disc from right to left, as viewed in Figs. 4 and 5. This is done against the action of the spring 134 and imparts a corresponding movement 7to the plunger 132 thereby relieving frictional contact between the clutch head 131 and the hub 91. This movement of the rod 139 also causes the outer end thereof to engage in the V-shaped notch at the end of the reproducer, swinging the same into the position shown in Fig. 5 wherein the needle 108 is brought into contact with the adjacentface of the record disc 100, between the periphery ofthe record and the first groove thereof. This is'done because of the varying distances between the (periphery of the first roove in various recor s. When the rod 139 1s moved from right to left by riding over the cam face 121 the frictional contact between the clutch head 131 and the hub 91 is not relieved until the and of therod is on the high portion of the face. of the cam 121. VConsequently as the rod rides between the recesses 120 and the cam face 121 the clutch head and hub are held in frictional engagement and the-needle after having made its initial contact with 'thel face of the record will ride from the position of this initial contact to the first groove of the record. lThe end portions of the rods 138 and 139 are preferably made of a material suliciently resilient to create a pressure between the rod and the reproducer which is sufficiently flexible or variable to permitpth'e parts to function intheir intended manner. -The hub 91 and the j parts associated therewithcontinue to turn, and the reproducer'arm and the parts carried thereby are nowffree to swing so thatv the needle 108 may track freely in the groovein the-face of the record disc 100. The reproducer and the needle are maintained in this' position by means of the rod 139 when shifted to the position shownr in Fig. 5, as hereinbefore described. In order that the needle may track freely in the groove of the face of the `record disk, the frictional contact between force'of gravity. It will be obvious that the reproducer maybe suitably placed in order to cause the same to be adequately maintained j in position to permit the needle to track in the groove of the record and to prevent the needle'from jumping from the groove of the record. It will be also understood that Aat this time thedisc 135 is in that position in which thepin140 on the rod 138 is free to 4 move in lts notch in the disc- 135, that is, irre-u spective ofthe action of the cam 115 the rod l138 remains inoperative. However, Vduring the playing of this record the inner end ofv the 'rod .138 can only bear against the low face of the cam. The inner end of the rod 139 remains in contact with the cam face 121 until the record has been played.4 In instances where the downward movement of the reproducer arml iswof sufficient extent to carry the end of the pin off the cam face 121 is coincident with the lengthv ofthe record, the end of theV pin then 'runs onto the low face ofthe cam and the rod is free, thereby .liberating thedisc 135 and permitting the spring 134 to again shift the. plunger 132 ciated therewith continuel to swing in this' return the reproducer to its normal or central' bringing the clutch head 131 into engagement with the hub 91 whereby, it will beA understood, the reproducer. arm and `parts assoclockwise direction. Of course when the end of the rod moves off the cam/face 121 thel rod being free permits theaction of the springs v 113 -and- 114to come into play and to thcreby position relativelyto the frame 102 in which l `it is pivotally mounted.- In' instances where the recorded record, is short the needle may reach the end of the groove therein before the inner end of the rod rides off the cam face 121. In such instances the cam 63 or 64 is. set so that the correspondingl cam` picks up the needle and the needle is carried along the cam in the same manner that it would have been carried by the record grooves until the point is reached in the travel 4of the reproducer arm for the end of the rod 139 to slide olf the cam face 121. This clockwise swingthen continued until the same reaches a substantially horizontal position on the-other side of the apparatus so as to actuate in one manner or another one of the cam devices 150 on the, shaft 149. Of course it will be i understood that irrespective of the shift eventually reversed so thatvthe reproducer arm agaln swings in the opposite direction.

which is effected at this time the parts are l.

the rod 138 is ,actuated by the cam onthe i guide arm 97 to swing and maintain the reproducer 103ina position in which the needle 107. tracks in the groove in a record. In this action thev inner end of the rod 138 bears against the cam face 117 carried by the guide arm 97 and the operation is otherwise similar to but the reverse of that hereilrbefore def scribed. Likewise, as will beunderstood, the

upward' movement of the reproducer arm carries the guide arm 97 lwith' it` and this oper- .ates the long arm 126 actuating. the short arm 127 to bearagainst the projection of the guide arm 99 so that these guide arms are again raised suiiicientlyrfar to be entirely free Y of the periphery of the discs. It is also to be noted that in moving upwardly to' shift the position of 'one of the carin devices 150 the end of the reproducer frame and the reproducer arm, due. to the initial or normal positionof the arm 153, carries the cam device suiliciently Vfar to remove the corresponding ball from one groove inthe cam device to permit it to move into the `next succeeding groove, where- .as in the. return or downward movement of the reproducer arm the projection at the end of the reproducer arm contacts with the next succeeding arm 153 of the corresponding cam device but does lnotl move' it suciently far to permit the ball to move over the rib between the grooves in the cam device whereby in the return movement -of the reproducer arm the cam device is merely rocked and no result is effected' thereby.

It will be obviously necessary to raise the tone arm after 'completing the obverse side of one record before beginningthe reverse, side ofthe nextadjacent record because the rotation ofthe disk records must be reversed in changing over from the playing of the record on one disk to the playing of the recordl on the other.` This is caused by the fact that the grooves in the record are made to extend from a. point adjacent the periphery to a point ad-` jacent the center thereof. Obviously, however, the record grooves might be made spe-' cial so that the grooves on the obverse face of one record might extend from a point Yadjal0 lng movement of the reproducer arm 1s sition in which this action takes place.

cent its periphery to a point adjacent its center and the grooves on the reverse side of the next adjacent record be made to start at a point adjacent its center and to end at a point adjacent its periphery. In so doing it would not be necessary to raise the tone arm or reproducer in successively playing the records on the obverse and reverse faces of .adjacent record disks. The apparatus made in accordance with my present invention, however, 1s

constructed to use record disks as ordinarily made although the changes necessary for the use of specially constructed records as hereinbefore indicated might be made without departing from'the nature and spirit'of my invention.

It Willbe understood, as hereinbefore stated, the cam devices 150 on the shafts 148 and 149 may be set manually to any desired position. As the reproducer arm swings upwardly, as hereinbefore last described, the corresponding cam devices 150 on the shaft 149 may be set in that position in which when the projection 112 at the end of the re roducer frame strikes one of the arms 153 o theI cam and blocks the same the movement of the cafm device will be insuiiicient to permit the corresponding ball to move over the projection or boss 156 and this initial movement of the cam device causes the projection 157 thereon to contact with the corresponding arm 198 on the shaft 196 thereby rocking the shaft andswinging the link 199 to move the arms 201 and 203'downwardly to depress the rod v208 thereby actuating the shift lever 84 and causing the clutch discs 7 6 and 79 to be separated and the clutch discs 72 and 82 to be brought together. This action causes the shaft 7 8 to `stop rotating and sets the shaft 81 in'motion.

The' reproducer arm will, therefore, be maintained in that relatively horizontal po- Upon the shaft 81 being turned, as will ,be understood, the carriage 85 will be shifted. The carriage continues to move until the projection 112 runs ofi' the arm 153 of the cam device with which it has been in engagement whereupon this cam device is free and is returned by the action of the corresponding ball 165 andthe spring actuating the same thereby releasing the proj ection'157 and permitting the arm 198 and the shaft 196 to re- 'turn Ato their normal positions, in doing which, of course, the arms 201 and 203 are raised by the action of the shaft 195, thereby again shifting the shift lever 84, releasing the shaft 81 and setting again in motion the shaft 7 8. In the meantime theprojection 220 vat the end of the.reproducer frame is advanced sufficiently far to come into contact with the corre onding proj ectin cam 154 of the next succeel ing cam device, t ereby turning the same a partial revolution. This partial-revolution of the. next succeeding cam device is eiected simultaneously. with or immediately after the re-shifting. of the shift lever and the re-setting in motion of the shaft 78 whereby, as will be understood, the rod 176 is reshifted and the shaft 78 is s'et in motion in the opposite direction, thereby causing the reproducer arm and the parts carried thereby to swing again in a counter-clockwise direction to play the record on the obverse face of the next succeeding record disc. This, of course, assumes that the travel of the carriage is from the rear to the front of the apparatus. Obviously thef reverse condition maintains from the front to the rear of the cabinet and to play the successive records when traveling in this direction. Obviously also the cam devices may be so set on the shafts 148 and 149 as to cause the omission of the playing of any one or more of the records, as may be desired.

The shaft 195 as illustrated in Fig. 1 may be provided with stop arms 223 and 224 which are adjustable to position thereon and with which the sides of the carriage are adapted to contact to limit the extent of the travel of the carriage either toward the front or toward the rear of the apparatus so that these parts may be set to determine the records, or sets of records, to' be played. As will be seen by reference to Flgure 1, the elevated portion of the rod 195 may be shifted to the right when the carriage-85 contacts with the stop arm 224. In so doing the arm 203 when moved downwardly will not vallow the rod 208 to rise and as will be understood travel of the carriage in t e movement thereof from left to right. Furthermore, the

spacer devices for the records may be fitted 'with long cams 225 and 226 which may be used alternatively withthe cams 63 and 64 lwhen necessary in order, as will be understood, to cause the needle to be guided by the in. causing the carriage to travel edge of one or the other of these long cams.

when it is desired to omit the playing-of the record on the face of any of the recorddiscs. As-will be ap arent the apparatus as hereinbefore described may be made for use merely as an ordinary phonograph or soundreproducing device, and may also be used in conjunction with a motion picture apparatus in which, of course, it is necessaryto so regulate the speed of the motor and the disc record shaftthat the' same will synchronize with the motion picture apparatus and as another instance of use the apparatus may be einployed in conjunction with a coin freed mechanism, whereby as desired the instrument may be played through the intervention of inserting a coin in a slot. In some instances it may also be advisable to furnish each one of the cam devices 150 with a numeral, or other index, so that it may be read- V to make the indices of thecam devices visible .the apparatus in a suitable position may be` provided with a mirror or other reiector, as

indicated at 227 in Fig. 3. It will now be understood that the cam devices and the other parts of the apparatus'may be set sopas to cause the automatic playing of any desired number of the records mounted on the record shaft in sequenceor in repetition, or as may be otherwise desired by theoperator.
